BVO Wire Grid Polarizer
The next great thing in Visible / NIR polarization. Use it as a 50/50 beamsplitter or regular transmissive linear polarizer. The 80 micron thickness means this film can be laminated to a variety of substrates such as polycarbonate, TAC, acrylic or glass. As a standalone film, BVO WG has very high environmental tolerances and can survive in harsh environments.
